Answer 2

To solve the given equation, let's break it down into two separate equations:

1. y + 2 = 7
2. (y - 5)(y + 9) = 0

First, solve equation 1:

1. y + 2 = 7

Subtract 2 from both sides:

y = 7 - 2

y = 5

Now, solve equation 2:

2. (y - 5)(y + 9) = 0

Now, set each factor inside the parentheses equal to zero and solve for y:

y - 5 = 0 or y + 9 = 0

For the first equation, add 5 to both sides:

y = 5

For the second equation, subtract 9 from both sides:

y = -9

So, we have three potential solutions for y: y = 5, y = 5, and y = -9.

However, notice that y = 5 appeared twice because it is a repeated root, and this is due to the factorization of equation 2. So, the actual solutions for the original equation are:

y = 5 y = -9

These are the values of y that satisfy the given equation.
